owncloud-server

I installed Ubuntu 14.04 on an old MacMini with the intention of running it as a homeserver. Additionally I installed ownCloud and tried to sync some files both from a laptop running elementaryOS and a desktop running windows 7.

Syncing smaller files workes like a charm (4000 files at <10mb each) but when it comes to bigger files (1 GB ubuntu iso e.g.) the upload failes after 20-100mb. I can't ping the server anymore and the server can't ping me. It still shows up in our router as connected though.

Disconnecting and reconnecting the wlan connection fixes the issue until the next attempt at syncing.

Edit: I also had to install the wlan driver with this manual: https://help.ubuntu.com/community/MacBookPro8-2#Wireless
